Strange PDF format?

Question

Data conversion

Hello. I came across a strange PDF file: rghost.ru/42035062
It does not open with anything other than an adobe reader, the rest of the software, when opening these 10 pages, displays succinctly:

Please wait…
If this message is not eventually replaced by the proper contents of the document, your PDF
viewer may not be able to display this type of document.
You can upgrade to the latest version of Adobe Reader for Windows®, Mac, or Linux® by
visiting www.adobe.com/products/acrobat/readstep2.html .

Actually, the question is: what kind of rubbish is this and how can this case be painlessly transferred to doc \ docx?

Answer 1

Here they write that the file may not be quite the good old PDF, but an XFA form. So far, only Adobe can read them ...

Answer 2

FoxIt reader opens your file wonderfully and even lets you edit form fields (and even saves their new values). Be careful when installing this free program - they try to shove all sorts of junk, like the Ask toolbar, but, fortunately, they give you the option not to do this by unchecking two boxes.
Unfortunately, only paid Adobe PRO can convert to doc\docx. The trial version can be downloaded from their website .
